'Hearts' in the Bible

For although they knew God, they did not glorify him as God or give him thanks, but they became futile in their thoughts and their senseless hearts were darkened.

Therefore God gave them over in the desires of their hearts to impurity, to dishonor their bodies among themselves.

They show that the work of the law is written in their hearts, as their conscience bears witness and their conflicting thoughts accuse or else defend them,

on the day when God will judge the secrets of human hearts, according to my gospel through Christ Jesus.

And hope does not disappoint, because the love of God has been poured out in our hearts through the Holy Spirit who was given to us.

And he who searches our hearts knows the mind of the Spirit, because the Spirit intercedes on behalf of the saints according to God's will.
